Make libunbound do such a specific query?  That is not its design.  It
performs recursive lookups and DNSSEC validation.

What you are looking for is perhaps ldns (nlnetlabs.nl/projects/ldns) in
which you can create an ldns_resolver object, and create a packet object
that you want to send out.  You then want to include this edns part into
the packet you send out with ldns_pkt_set_edns_data().
